MySQL is an open-source relational database management system (RDBMS) owned by Oracle. Before Oracle acquired the product, it was completely free for users. After the merge, the solution started offering paid services with more features, alongside a free version. MySQL can easily integrate with a wide variety of programming languages, which makes it one of the most flexible and reliable products among its competitors. This cost-effective solution helps users deliver high-performance and scalable database applications through several products. They include:
-
MySQL HeatWave: This is an in-memory query accelerator for MySQL. It is a parallel, columnar, hybrid query-processing engine with algorithms for distributed query processing. This database service is used for transactions, analytics, and machine learning (ML). It offers simplified, secure real-time analytics. It can be deployed on Oracle Cloud Infrastructure (OCI), Amazon AWS, Azure, and users' data centers.
-
My SQL Enterprise Edition: This edition of the solution includes the most comprehensive set of advanced features, technical support, and management tools. The combination functions achieves security, scalability, reliability, and uptime, while reducing risk, cost, and complexity, in managing MySQL applications.
-
MySQL Standard Edition: This edition utilizes industrial-strength performance and reliability to help users deliver high-performance and scalable Open Transaction Processing (OLTP) applications.
-
MySQL Classic Edition: This is an embedded database for independent software vendors (ISVs), original equipment manufacturers (OEMs), and value-added resellers (VARs), that are developing applications using the MyISAM storage engine.
-
MySQL Community Edition: This is the free version of the product, which is supported by a large active community of open-source developers.
-
MySQL Cluster CGE: This is a distributed database that combines linear scalability and high availability. It offers in-memory real-time access across partitioned and distributed databases.
-
MySQL Embedded: This product offers MySQL as an embedded database and is most widely used by ISVs, OEMs, and VARs. It is utilized for making applications, hardware, and appliances more competitive by bringing them to market faster while lowering their cost of goods sold (COGs).
My SQL Features
The characteristics of each MySQL edition differ depending on what it offers and what clients it is catered towards. But the main features of the product include the following:
-
Internals and portability: These capabilities allow MySQL to work on multiple platforms and provide transactional and non-transactional storage engines. This set of features is tested with Purify, Vilgrind, and a broad range of different compilers.
-
Data types: Due to the flexibility of the data types feature of MySQL, the product is compatible with a very wide variety of data types, including fixed-length and variable-length string types.
-
Statements and functions: This feature allows MySQL full operator and function support. It supports a wide variety of functions and allows users to refer to tables from different databases in the same statement.
-
Security: The security features of MySQL provide users with a flexible privileged password system that enables host-based verification. The product offers encryption of all password traffic when users connect to a server.
-
Scalability and limits: MySQL supports large databases with up to approximately 50 million records and up to 64 indexes per table.
-
Connectivity: The connectivity features of the product allow clients to connect to MySQL using several protocols, providing them with freedom of choice in terms of which ones to use.
-
Localization: Through this feature, the product offers availability to users in many languages. The server time zone can be changed dynamically and allows clients to specify their own time zone for their convenience.
-
Clients and tools: The product includes several client and utility programs among its capabilities.
MySQL Benefits
MySQL brings many benefits to organizations that use it for their data. The most common ones include:
- Due to its initial open-source nature, MySQL is an easy to understand and beginner-friendly product.
- The solution still supports an open-source version as well, which means users can download, use, and modify it based on their requirements.
- MySQL ensures the consistency of data by storing it efficiently and minimizing redundancy.
- This is considered one of the fastest solutions on the market, a fact which is backed by many benchmark tests.
- MySQL is very flexible and supports a large number of embedded applications.
- The solution is compatible with many operating systems.
- This product offers clients the option to roll back transactions, as well as commit, and crash recovery.
Reviews from Real Users
According to a database engineer at a retailer with more than 10,000 employees, MySQL is a great open-source product that offers great scalability and compatibility.
Yong S., a solutions specialist, system integration, appreciates this product because it has different licensing options and is easy to set up.
Noms is a decentralized database philosophically descendant from the Git version control system.
Like Git, Noms is:
Versioned: By default, all previous versions of the database are retained. You can trivially track how the database evolved to its current state, easily and efficiently compare any two versions, or even rewind and branch from any previous version.
Synchronizable: Instances of a single Noms database can be disconnected from each other for any amount of time, then later reconcile their changes efficiently and correctly.
Unlike Git, Noms is a database, so it also:
Primarily stores structured data, not files and directories (see: the Noms type system)
Scales well to large amounts of data and concurrent clients (TODO: benchmarks)
Supports atomic transactions (a single instance of Noms is CP, but Noms is typically run in production backed by S3, in which case it is "effectively CA")
Supports efficient indexes (see: Noms prolly-trees)
Features a flexible query model (see: GraphQL)
Finally, because Noms is content-addressed, it yields a very pleasant programming model.
Working with Noms is declarative. You don't INSERT new data, UPDATE existing data, or DELETE old data. You simply declare what the data ought to be right now. If you commit the same data twice, it will be deduplicated because of content-addressing. If you commit almost the same data, only the part that is different will be written.
